The RVL-CDIP corpus consists of grayscale images of scanned documents from the IIT-CDIP collection [1]}, a large repository of publicly-available documents that were released as part of litigation against several tobacco-related companies and organizations.
As such, all documents in the RVL-CDIP corpus are tobacco-related.
The corpus consists of 16 categories: advertisement, budget, email, file_folder, form, handwritten, invoice, letter, memo, news_article, presentation, questionnaire, resume, scientific_publication, scientific_report, and specification.
Samples from RVL-CDIP are shown in Figure REF .
We note that many of the RVL-CDIP samples contain visual noise introduced by scanners due to having been scanned from the physical world using old or noisy document scanners.
Each RVL-CDIP category has 20,000 training samples (320,000 total training samples), and there is a total of 40,000 validation and 40,000 test documents across all categories.
All documents from this dataset are from the year 2006 or earlier, as 2006 was the year that the IIT-CDIP collection was released.
